T 0 all whom it "may concern:

Be it known that I, iiLrnnn P. SLoAN, Jr., a citizen or the United States, residing at No. 275 Clinton avenue, Brooklyn, county of Kings, and State of New York, have m-- vented certain new and useful Improvements in Steel-Lined RollenBcarings, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to furnish an improved construction whereby a steel lining can be applied economically to a cast metal casing having integral 'llanges at opposite ends. for use in a hanger-lung. Such cast metal casings have lu-iretohne been made opt-n at one end to facilitate the introduction of a boring tool or cutter for truing out the cvlindrical seat which supports the slruction necessitates the ftuning of a flange to a box, which flange is liable to become looscnod.

In the present invention. the flanges are made integral with the casing, and the boring is etlccted bv forming recesses within the casing near its opposite ends of suflicient diameter to clear the boring cutter. The casing is made in hz lvcs with bolting lugs to clamp the luilvcstogcthcr around boring bar carr g a suitable cutter, which enters one of one recesses, the casing or bar bein then fed longitudinally and the cutter traversed from. one of the recesses to the other, thus boring out the seat for the lining.

The lining is prepared for application to the casing by i'oriningit in halves and clamping the halve in a suitable clamping box under a boring tool, which is then fed through the lining to bore its interior. The halves of the lining are furnished each near one end with a hole which its a stud in the clamping box to hold the lining from rotation duringithe boring operation. and such holes are located to coincide with oil-holes upon the casingwhen the lining is fitted therein. The lining extends from one flange to the other within the casing and thus covers the recesses and furnishes a continuous support for the anti-friction rolls.

In the drawing, Figure 1 is plan of the roller bearing adapted for a hanger-hon; Fig. 2 is a cross section of the same on line 2, 2, in Fig. 1, with the anti-friction rolls and a shaft fitted therein; Fig. 3 is a vertical section got the same with the boring-bar and cutter ara designates the casing which is formed in halves and provided with the flanges b and b, which cover the ends of the anti-friction rolls 1", which are shown only in Fig. 2 With the roll-guide. 1". A narrow recess 0 is formed in the casing contiguous to the flange 7), and a relatively wider recess (1 is formed at a little distance from the flange l), the recess d being made of larger diameter and greater width than the diameter and thickness of the cutter O, which is shown in Fig. 3 mounted upon a driving. mandrel on boring-bar D. I

To prepare the casing to receive the lining f, the cutter is first traversed from the recess d to the flange b, forming a short seat f to support one end of the lining and truing off the inner side of the flange 6, against which the end of the anti-friction rolls or their guide, rotates. The cutter is then traversed from the recess (Z to the recess 0, forming the seat c and facing ofl the inner side of the flange b. The recess 0 makes a clearance space for the chips which are formed by the cutter in facing the flange I); while the recess 2 forms a clearance for the cutter when the casing is boltcdtogcther over the same be-- fore any of the seats have been bored. the lower half of Fig. 3, the lining is shown extended the whole length of the casing, the lower edge of the cutter being broken away to clear the same; but in the upper half of 9 Fig. 3, the casing is shown in the right hand half without the lining, and the material .in dicated by the dotted lines e, which would. be removed by the cutter to produce the re quirei'l seats for the lining and rolls. The halves of the casing being unbolted can then he removed from the cutter C and mandrel D, and are in readiness to receive the lining. The lining is made of two tapering blanks F, as shown in Fig. 7 ,each forming one half of the lining f when rolled to semi-cylindrical shape. 1

A hole 7:. or 71. is punched in the middle of each blank near one-end, and the halves are then fitted togcth er, with their wide and her row ends adjacent inside a clamping hex A, shown in Fig.' 6, which is provided with studs B to fit the holesh and h and thus hold the lining from turning. A boring" tool it is represented diagrammatically in Fig. 6, which, when forced downward in the lining serves to here the same out in readiness to support the anti-friction rolls. When thus bored, the halves of the lining are fitted into the halves of the casing, as shown in Fig. 1, and in the left hand end of Fig. 3, and secured therein by rivets 0.

The holes g and g in the casing: are so located as to coincide with the holes in the two halves of the lining, which are marked 7i and h in Fig. 3, and the oil-hole g upon the top of the casing; is formed with an upwardly projecting collar 7), adjacent to which a hinge-- lug 'i is formed upon the casing. A cap j is hinged upon the lug i and provided with rearwardly j'nojccting toes /w which prevent the cap from being lilted into a vertical position, itis thus compelled, after being lifted, to fall baclc upon the collar and close the oilhole. The cap is formed with a llai'ig'e Z which surrounds the collar 7) when the cap is closed, so as to exclude dust li'oin the oihhole g, and the llange Z is formed at intervals with notches Z which permit the nozzle oi an oil can to beinserted through the notches when the cap is partially raised and oil thus lurnishod to the oil-hole 9' without raising the cap very far. This is an advantage in the case of lianger-hoxes where the hangers are attached to the ceiling, and access to the cap and oil-lmles is frequently obstructed. The oil-hole g in th hottoin ol' the casing perinits the worn or waste oil to drain out ol' illibearing. 1

The blank l l'or the lining shown in Fig. 7 tapered toward both ends. and when two such blanhsare put together with the wide and narrow ends in contact, they can he rolled to l orin a complete cylinder with oblique joints at opposite sides ol the Saint. Such oblique joint in the lining: issliown at in Firs. I) and (i, and permits the ante 'friction rolls to move smoothly over the joint, and thus prevents any jar which would he oc .asioned ii the oint were parallel with the more and the ntire length ol the roll thus crosses the joint at once.

ln l ig. 2, the division between the two parts of the casino is arranged vertically, by the pro ection oi" this view lroin th plan. in Fig. 1, and it will be observed that the joint ol the sheet-steol lining in lig. 2 extends at both sides above the halves o l the casing.

Fig. 3 shows that, at the opposite end of the box, the joint of the lining is below tindivision between the halvesol the casing; and the tapering Form of the two blanks from which the lining is made thus causes the joint between the linings to project, at opposite ends of the easing, into opposite halves of the same, which assists materially in sup orting, the joint of the lining, as such joint c oes not no incide with the division or joint of the casing. The oblique joint of the lining thus performs the double function in easing the retation of the anti-iriotion rolls, and in steadying the joint of the lining.

It will be observed that in the finished article both the casing as Well as the lining is furnished with a finished cylindrical bore, which assists materially in supporting,the lining with firmness and holding its finished surface truly in cylindrical shape.
